Wujie Dam is a concrete gravity dam on the Zhuoshui River in Ren'ai Township, Nantou County, Taiwan. The dam was built in two stages, from 1919 to 1922 and 1927–1934, and serves primarily to divert water from the Zhuoshui River to a storage reservoir at Sun Moon Lake and its associated hydroelectric projects (Mingtan Pumped Storage Hydro Power Plant and Minhu Pumped Storage Hydro Power Station). During the Japanese occupation of Taiwan it was known as Bukai Dam.
The dam is located in a narrow gorge about northeast of Sun Moon Lake. It is high and 86.5m (283.8feet) long, forming a reservoir with a design capacity of 14000000m2, now mostly silted up. The diversion tunnel to Sun Moon Lake has a diameter of 3m (10feet), with a diversion capacity of 40.35m3/s. The spillway of the dam consists of six gates with a capacity of 3150m3/s.[1]
